Question
Parallel plates form a solar collector that covers a roof, as shown in the figure. The
plates are maintained at 15°C, while ambient air at 10°C flows over the roof with V=
1.4 m/s. The properties of air at the film temperature of (15 + 10)/2 = 12.5°C are k=
0.02458 W/m.°C, v = 1.448 × 10−5 m²/s, and Pr = 0.7330.
